Vision recognition reads custom-drawn desktop controls, dense grids, terminals and web pages like a person, so one plain-English step runs on every channel. When a screen changes, you approve one fix. [Book a demo](https://qventis.ai/contact#demo)[See desktop testing](https://qventis.ai/solutions/legacy-desktop?hsLang=en) - Reads screens like a person - Same result every run - Web tests export to Playwright **Approve a purchase order**Desktop, 5 steps 1. Open the 'Procurement' app 2. Type '{{po.number}}' into the 'PO number' field 3. Set cell 'Qty' to '5' on that row 4. Click the 'Approve' button 5. Check that 'Status' shows 'Approved' within 3 seconds ## Write it once, run it anywhere ### One sentence, every channel Each step compiles for the channel you run on. No CSS, no XPath and no rewrite per channel. ### Zero AI tokens at run time Steps compile once into deterministic code. Cost stays predictable and every run leaves the same audit trail. ### Heals you approve Each target is stored once by label and role. When a control moves, the engine proposes a heal with evidence and a person approves it. ## How the functional engine works ChannelsDesktop, terminal, web, API and mobile VerbsSame meaning on every channel RolesWhat each team member gets One model, one paneShared map, one results view ### Every channel, one language The same sentence runs wherever your users work, including screens that other tools cannot see. - Desktop: Windows apps, with vision recognition for custom-drawn controls and dense grids - Terminal and remote sessions: green screens and Citrix, read from the pixels - Web: browser apps with a recorder and the Studio editor, run on Playwright - API: REST calls, payload checks and values passed between steps - Mobile: native and hybrid iOS and Android apps, run on Appium or Maestro [Legacy desktop testing](https://qventis.ai/solutions/legacy-desktop?hsLang=en) ### Shared verbs everywhere Open, Click, Type, Select, Tick, Choose, Press, Wait for, Remember, Check, Use and Repeat mean the same thing on every channel. A sentence that doesn't parse is not a step. - Targets are a quoted label and a role noun, never a locator - Check captures what was expected, what was found and a screenshot - Channel packs add only the verbs a channel needs, such as a swipe on mobile [See the packaged app packs](https://qventis.ai/engines/packaged-apps?hsLang=en) ### One suite for every role The people who know the business and the people who ship work from the same steps. - Business testers record a flow and read it back as sentences - QA leads fix a target once and every test that uses it follows - Release managers open the evidence behind each check - SDETs run headless from CI/CD and export web tests to Playwright [Explore Studio](https://qventis.ai/platform/studio?hsLang=en) ### Where the App Model starts The screens, controls and flows you record here become the shared map in the [App Model](https://qventis.ai/one/app-model?hsLang=en) that every engine uses. - Performance replays your functional journeys - Security reuses your roles and screens - Accessibility and visual checks attach to the same screens - Every result lands in [Quality View](https://qventis.ai/one/quality-view?hsLang=en) with its evidence [Explore the App Model](https://qventis.ai/one/app-model?hsLang=en) ## Questions Do I rewrite tests for each channel? No. The core verbs work on every channel. You add pack verbs only where a channel has an action the others don't. Can I take my tests with me? Yes. Web tests export to Playwright, assets are Git-friendly, and every component works through the CLI and SDK. ## Bring your hardest app Watch it automated Bring a desktop, terminal or web flow and leave with plain-English steps running against it.
